Hi there.
00:02
In this question, we are given this balanced chemical equation.
00:06
And balanced chemical equations are very useful because they give us the mole ratio.
00:11
The mole ratio is the ratio in which the reactants react and the products are formed.
00:17
And the mole ratio comes from the coefficients in our balanced equation.
00:22
Well, in our balanced equation, we don't have any coefficients written.
00:25
So it is understood they are all ones.
00:29
That means our mole ratio tells us that for every 1 mole of the csf that reacts, we need an equal amount of the xef6.
00:43
And in turn, this would produce 1 mole of the product.
00:49
Alright, so we just have a 1 to 1 to 1 ratio.
00:51
In this question, we are told that we're reacting 12 .5 moles of the csf and 10 moles, 10 .0 moles, of the xcf6.
01:10
And we want to know how many moles of the product we can make.
01:16
Well, this is a limiting reactant problem.
01:20
Limiting reactant refers to the reactant used up first.
01:32
Once that reactant is used up, the reaction will stop because it can't proceed if we don't have each of our reactants.
01:44
Therefore, it limits how much product can be made.
01:47
So we need to figure out which one here is our limiting reactant...
